[Madwifi-users] ath5k kernel oops
|
From: Joo A. S. <ja...@ya...> - 2009-03-30 03:04:52

Hello,
I'm getting kernel oops when modprobe ath5k on kernel 2.6.29 on ARM
big-endian platform. PCI card is Atheros AR5413 168c:001b (rev 01).
Sometimes I don't get kernel oops, I get this instead:
ath5k phy0: failed to warm reset the MAC Chip
I've added a few debug messages in the driver, in file reset.c,
function "static int ath5k_hw_nic_reset(struct ath5k_hw *ah, u32 val)",
before and after this function call "ath5k_hw_register_timeout(ah,
AR5K_RESET_CTL, mask, val, false);"
data = ath5k_hw_reg_read(ah, AR5K_RESET_CTL);
ATH5K_ERR(ah->ah_sc, "Check reg: 0x%x + 0x%x, mask: 0x%x, val:
0x%x, data: 0x%x\n", (int)(ah->ah_iobase), AR5K_RESET_CTL, mask,
val, data);
From the debug messages, I don't understand why I'm getting kernel oops. Can anyone help me? Thanks.
This is my kernel trace with a few of my added debug messages:
